Specification of Letters Patent.

Patented Apr. 240, 11915.

Application filed July 23, 1914. Serial No. 852,745.

To all whom it may concern Be it known that I, JABEz M. SMITH, a citizenof the United States, residing at Malvern, in the county of Hot Springsand State of Arkansas, have invented a new and useful Vehicle-Tire, ofwhich the following is a specification.

This invention relates'to improvements in vehicle tires and particularlyto that type of tire utilizing a plurality of spring convolutionswhereby the desired resiliency is obtained.

One of the objects of the present invention is to provide an improvedmeans for securing the separate springs to the rim so that they may bequickly attached or detached, as desired.

A further object is to fashion the springs of such cross sectionalcontour that they will possess the desired resiliency, the constructionbeing such that the springs may be used in connection with a shoe or maycontact directly with the road.

A further object is to provide a tire embodying separate and distinctspring loops over which extends a shoe, which shoe may be easily andquickly secured to the spring loops and be readily detached therefrom tofacilitate the repairing of one or a number of the loops.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings accompan ing this specification and forming a partthereof, the preferred embodiment of my invention is illustrated.

In said drawings: Figure 1 is a view in cross section of a wheel rimwith my improved tire secured thereto. Fig. 2 is a side elevation of theforegoing with a portion of the outer casing removed, in order todisclose the spring elements. Fig. 3 is a fragmental perspective of oneof the spring loops. Figs. 4 and 5 are transverse sectional views of aspring element, the latter figure disclosing the spring element asprovided with a casing riveted thereto.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, the

structure depicted in Fig. 1 includes a rim 10 provided at its edgeswith outwardly extending flanges 11, the same being inclined one withrespect to the other at an angle of substantially 90 degrees and thusdefining with the rim 10 an angle of substantially 135 degrees.

The tire is made up of a plurality of separate loops 12, each loopincluding a circular portion 13 extending through substantially definedby a plane lower wall 17 and the curved outer portion 18. A casing 19may encompass the spring and when such is the case the part 19 issecured to the spring by rivets 20. An outer shoe 21 may be secured byrivets R to the spring loops, as disclosed in Figs. 1 and 2. In any casethe shoe may be detached from the spring loops, allowing the latter tobe replaced, thus permitting the tire to be repaired from time to time.

It is to be observed that the device herein disclosed comprises a rim 10having inclined flanges 11; a curved spring element 12 comprising a bodythe lateral portions of which are bent to form S-shaped flange receivinghooks l4 defining upper and lower walls, the upper wall lying againstthe upper face of one flange 11 and the lower wall of the hook lyingagainst the lower face of the said flange; and a securing elementrepresented by the bolt 16, the bolt 16 passing through both walls ofthe hook, the bolt having a head which engages the inner wall of thehook. Mounted upon the bolt is a movable means, represented by a nut,which nut engages the outer wall of the hook. The bolt 16 is of greaterlength than the distance between the lower face of the upper wall of thehook and the body of the spring,

.whereby the bolt may remain engaged with the flange when the nut isdetached. The spring element 12 is yieldable to permit the insertion ofthe bolt through the walls of the hook and through the flange.

Having thus fully described my invention, what I claim is 1. In a deviceof the class described, a rim having inclined flanges; a curved springelement the lateral portions of which are bent to form S-shaped flangeengaging hooks defining spaced walls, one of which walls lies againstthe upper face of one flange, another of which walls lies against thelower face of said flange; and a securing element passin through theflange and engaging both 0 said walls of the hook to clamp the same onthe flange.

2. In a device of the class described, a rim having inclined flanges; acurved spring element comprising a body the lateral portions of whichare bent to form S-shaped flange receiving hooks defining upper andlower walls, the upper Wall of the hook lying against the upper face ofone flange and the lower wall of the hook lying against the lower faceof said flange; and a securing element passing through the flange andthrough both walls of the hook, said securing element having a headwhich engages the inner wall of the hook; and movable means on thesecuring element for engaging the outer wall of the hook; the securingelement being of greater length than the dis- JABEZ M.
